I work in a book store and we sell a lot of (and get a lot of positive feedback on) Allen Carr's Easy Way to Stop Smoking. I've never smoked, but people have told us that this book is very effective. Maybe tell her to have a look at it?

I will. Thank you.
Working in bookstores is great and I wish I still could. Have a great day.

I heard chewing gum helps.

I'm sure any gum would help at least some.

Good idea, and it rhymes!

One of those electronic cigarettes? I'd treat them more as a last resort though...

Chewing gum helps with the oral addiction, but won't do much for the nicotine. It's a good thing to add to the rest of your regimen if you haven't already, though.

Just don't do it. Worked great for me.
Seriously... if you don't want to stop, you'll fail no matter how many patches you use or how much gum you chew. This stuff only reminds you of how bad you are addicted (I smoked for ~9 years if anyone cares).

Just dont buy them, when I quit i told my local shop not to sell me them that I was quiting, and they wouldnt sell me them. the next closest shop is 30 min drive so screw that

This.

If you're prone to addiction, you get two choices. You can continue on to your own ill health, or you can stop and suffer through the constant nagging of wanting that something all the time. You can maybe shore up the first choice with medication if you're lucky.

Life sucks like that, when the choices are to either give in or suck it up and deal with it.

To the people who can easily pick up and then drop an addiction like it was no thing, those are the extremely lucky ones. If this isn't you, best not to try to measure yourself to them at all, or you'll get discouraged with a quickness.

Nicotine-detecting shock collar.

Watch Stephen King's Cat's Eye. The first short about quitting smoking is brutal.

That's going to make it tougher. You're probably going to just have to keep plugging at it until your successful. Meaning that if you relapse, you make it your last cigarette and start over.

Also, if you're in a part of the world where they allow in business places, I'd avoid as many of those as possible, and try to spend most of the time with people that don't smoke.

Pick up a bag of sunflower seeds every time you feel the need to smoke start chewing on them.

Here are my own little tips that might help...I think they helped me.

-I stayed far away from people who smoke, and asked my friends not to smoke around me. Most respected that.
-I would smoke a lot in bars, while drinking...so I stopped going to bars and drinking.
-I would take breaks to smoke at work. Rather than smoking, I used my breaks to take short walks. Exercise helps, seriously.
-I rewarded myself for quitting smoking. I thought, what will I do for myself if I accomplish this VERY difficult thing? For me, I wanted a new guitar. I didn't let myself buy it until I was smoke free for a couple months. It gave me more incentive to struggle through.

As others have said, you really, really have to want to stop. Most smokers have to quit (and fail) many times before they succeed. Best of luck to your friend...it's a hard addiction to break.
